Aquaporin-11; Channel protein that facilitates the transport of water, glycerol and hydrogen peroxide across membrane of cell or organelles guaranteeing intracellular homeostasis in several organes like liver, kidney and brain. In situation of stress, participates in endoplasmic reticulum (ER) homeostasis by regulating redox homeostasis through the transport of hydrogen peroxide across the endoplasmic reticulum membrane thereby regulating the oxidative stress through the NADPH oxidase 2 pathway (By similarity). Plays a role by maintaining an environment suitable for translation or prot [...]

Aquaporin; Aquaporins facilitate the transport of water and small neutral solutes across cell membranes.

Aquaporin-8; Forms a water-specific channel; mercury-sensitive. It may have an important role in spermatogenesis, in fertilization, and in the secretion of pancreatic juice and saliva; Belongs to the MIP/aquaporin (TC 1.A.8) family.

Lens fiber major intrinsic protein; Water channel. Channel activity is down-regulated by CALM when cytoplasmic Ca(2+) levels are increased. May be responsible for regulating the osmolarity of the lens. Interactions between homotetramers from adjoining membranes may stabilize cell junctions in the eye lens core. Plays a role in cell-to-cell adhesion and facilitates gap junction coupling (By similarity).

Aquaporin-4; Forms a water-specific channel. Plays an important role in brain water homeostasis and in glymphatic solute transport. Required for a normal rate of water exchange across the blood brain interface. Required for normal levels of cerebrospinal fluid influx into the brain cortex and parenchyma along paravascular spaces that surround penetrating arteries, and for normal drainage of interstitial fluid along paravenous drainage pathways. Thereby, it is required for normal clearance of solutes from the brain interstitial fluid, including soluble beta-amyloid peptides derived from [...]

Aquaporin-1; Forms a water-specific channel that provides the plasma membranes of red cells and kidney proximal tubules with high permeability to water, thereby permitting water to move in the direction of an osmotic gradient; Belongs to the MIP/aquaporin (TC 1.A.8) family.

Aquaporin-2; Forms a water-specific channel that provides the plasma membranes of renal collecting duct with high permeability to water, thereby permitting water to move in the direction of an osmotic gradient. Plays an essential role in renal water homeostasis (By similarity).

Aquaporin-5; Forms a water-specific channel. Plays an important role in fluid secretion in salivary glands. Required for TRPV4 activation by hypotonicity. Together with TRPV4, controls regulatory volume decrease in salivary epithelial cells. Seems to play a redundant role in water transport in the eye, lung and in sweat glands (By similarity).
